Parallel port extension?

[HakBot]

Hello,

I am trying to set limit switches up on my taig mill. Im running a xylotex 3 channel controller and have wired the switches up like what is pictured on this page: http://www.xylotex.com/PDFS.htm

I purchased a "parallel port extension" from a local computer shop. It works fine for controlling the xylotex board but does not work for the limit switches input. By checking the resistance i found that only the first 8 pins are connected all the way through the cable. (pins 2-9 on the port). Accoding to xylotex (http://www.xylotex.com/System.htm) these are in fact the pins needed to drive the board so this explains why I am able to control the motors fine.

Is this a common thing with parallel port extensions? Other than building my own cable, is there somewhere I can get a fully connected (all pins) parallel port extension?

Yes, they only wire the pin needed for most printers, same goes for DB25 serial plugs, you are better off doing one by yourself... // ports are going the way of the dinosaurs, finding a good fully wired cable is a waste of time compared to doing your own...
